A Major Defficiency in Auto Web Sites

I am in the market for a new car, as I have a 16 year old soon-to-be licensed driver. Don't get me started on the insurance costs..... Anyway, with a large family, I have special requirements (at least five seats). As I have scanned and scanned new and used car web sites, I have not found, on a single site, how many can fit in a car. No listing of number of seat belts, no listing of number of passangers, nothing. I have looked in the build section, in the specifications, on the front pages, nothing. I challenge the web site designers and marketers to fix this greivous deficiency.
